Patents can be declared: if there are only differences in patterns, characters and colors between different packaging boxes, patent for appearance can be declared; If the structure is different from other packaging boxes, you can declare a utility model patent.
according to the patent law of the people's Republic of China, there are three kinds of patents:
first,? Invention patent. Invention refers to a new technical scheme proposed for a product, method or its improvement. The packing box is not a new product, and it does not involve technology or method, so it is impossible to declare an invention patent.
second,? Patent of utility model. It refers to a new practical technical scheme for the shape, structure or combination of products. The shape, structure or combination of the packaging box can produce new functions, achieve the functions that other packaging boxes do not have, meet the use requirements that other packaging boxes cannot meet, and can apply for utility model patents.
third? Design patent. It refers to a new design that is aesthetically pleasing and suitable for industrial application, which is made on the shape, pattern or their combination of products and the combination of color and shape and pattern. Most enterprises have many combinations of shapes, patterns or colors, which will be different from those of other products, so they can declare utility model patents.
